@wylldflower5628 Not sure what "new thinking" applies here. All in rough approximations: plates move on the order of 1 to 3 centimeters per yr relative to each other, but they 'stick' grind and flex (wind up) near faults.
Intuitively, they make up for a century or 3 all at once when they rupture, longer the wait the bigger the slip/energy released.
4 or 6 on Richter Scale are tiny compared to an 8, a 9 is more than 10X bigger than an 8. On the higher end, sudden offsets of several meters happen. (Problem with log scales is ppl don't understand them, but otherwise we'd be talking about a 10 to a 1M quake)
4 is barely perceivable, a 6 won't likely wake you up, a 9 may level your house but certainly will define your yr if nearby.
Plates are driven by viscous magma under the influence of massive convection currents, they can only move so fast, reliving the stress won't have much effect on average plate movement.
Stands to reason that if you could frack entire fault line, say('grease' it hypothetically), gradual movement is safe, pent up energy, wound spring release is not.
